MBS impact modifier

MBS Impact Modifier, also known as MBS resin, is a copolymer comprising methyl methacrylate, butadiene, and styrene. Its compatibility with PVC is remarkable due to a solubility parameter ranging from 94 to 95, closely matching that of PVC. MBS Impact Modifier can improve impact performance, tensile strength, elongation at break, transparency, and light transmittance, often exceeding 90%. However, it should be noted that this modifier exhibits limited heat resistance and weather resistance, making it less suitable for long-term outdoor applications.
